System Providing Mote Network Emulation of One or More Legacy Sensor Devices

FIG. 1 is a block diagram of an embodiment of a system providing mote network emulation of one or more legacy sensor devices.

A mote network within a volume/area 117 includes multiple mote sensor/processors. For purposes of illustration, three motes 102, 103, and 104 are shown, although in practice the network could have more or fewer (typically more) motes. Mote 103 is shown in more detail, having a communication interface 106, an environmental sensor 107, and other logic 109 to carry out/participate in various acts as described herein.

The system further includes at least one external device 111 having its own logic 113 to carry out/participate in acts described herein, and at least one legacy device 119 adapted to interact with non-mote (a.k.a. legacy) sensors. The device 111 may include an interface 121 to interact with the device 119 by emulating one or more non-mote sensors.

Readings may be collected from a number of mote sensors (e.g., one, two, three, etc., mote sensors) of a mote network (henceforth, “data collection”), the mote sensors located at a number of mote sensor locations. A number of “legacy” (a.k.a. non-mote) sensors may be emulated as a source or sources of the readings (henceforth, “sensor emulation”). In systems where the location of the legacy sensors is a factor, legacy sensors may be emulated to be at particular locations.

Sensor emulation may include and/or involve emulating, as a source or sources of the readings, a number of sensors at a number of sensor locations different than the number of mote sensors. For example, a large room may be created by merging two rooms (e.g. removing a wall), each room having a thermocouple connecting to the heating system. The thermocouples may be removed as part of the renovation, with the wires to the thermocouples remaining. To replace the removed thermocouples, a large number of motes (say, 80 motes, including motes 102-104) having temperature sensors may be placed in locations throughout the room. The interface device 111 may be attached to the thermocouple wires to the heating system. Furthermore, sensor emulation may include emulation of another mote network; for example, a new mote sensor network might emulate an old (e.g., failing) one.

Emulation information may be provided to the device 111 in order to enable the device 111 to emulate the removed thermocouples using readings from one or more motes of the mote network. One or more of the motes may communicate temperature readings to the device 111, which may apply logic 113 to emulate the thermocouple readings using the mote readings. The device 111 may convert the mote readings to analog signals compatible with the legacy thermocouple wires and may communicate these signals using the wires to the heating system.

Thus, data collection may involve collecting readings from a number of mote sensors more or less than the number of sensors being emulated. There may be various manners of implementing data collection, including but not limited to collecting readings from at least one mote sensor at a location different than any of the sensor locations. A single sensor may be emulated, possibly at a single location such as location 131, or more than one sensor of the same or different types may be emulated. (See the previous example for a collection of a large number of motes that emulate in this case, two thermocouples).

Sensor emulation may involve improving upon an accuracy of readings that would be provided by the sensors. Greater accuracy may be accomplished by collecting readings from a number of mote sensors greater than the number of sensors. Thus, in the previous example, emulation of two thermocouples by a large number of mote sensors may, in some situations, increase the accuracy of the temperature readings, through statistical averaging and other techniques, by an order of magnitude or more over what the sensors themselves could provide.

As a second manner of accomplishing greater accuracy, the mote sensors may use a different physical technique to obtain their readings than that of the emulated sensors. In the previous example, the thermocouple sensors which were replaced typically may not have measurement accuracy appreciably greater than 1 degree centigrade. The mote sensors may be thermistors, which use resistors to develop temperature readings, and may be an order of magnitude or more accurate than thermocouples.

Readings may be collected from two or more mote sensors of a mote network in different locations. One or more readings may be derived from these collected readings, where the derived readings emulate readings from at least one non-mote sensor in at least one non-mote sensor location.

Besides replacing previously used sensors with a network of mote sensors, mote sensors emulating some other type of sensor can obviously be used in new installations which would ordinarily use the other sensor.

Network Adaptation

Various aspects of the data collection and/or emulation may be adapted to improve accuracy and/or account for environmental factors such as mote failures (henceforth, “network adaptation”). For example, the number of mote sensors, the number of mote sensor locations, and/or the mote sensor locations may be adapted to account for one or more mote sensors that were providing readings but which have failed. Network adaptation may be caused by external logic (e.g. logic 113) or by the mote network itself (a.k.a. the mote network is “self-adapting”).

Network adaptation may include and/or involve changing at least one of the mote sensor locations to improve the accuracy of the emulation of the sensors (henceforth, “location adaptation”). Location adaptation may be caused by external logic (e.g. logic 113) or by the mote network itself (a.k.a. the mote network is “self-adapting”).

Network adaptation may be performed to account for changes to one or more of the mote sensor locations, accuracy of the emulating of the number of sensors, performance of the emulating of the number of sensors, or to changes in the environment of the mote network. As an example where a changed mote position may result in network adaptation, a mote which is providing readings used in sensor emulation may be dislodged from its position, say the underside of a table, and fall to the floor. Its readings may then be lower, as the cold generated by air conditioning in the location is most intense on the floor. The system may recognize directly that the location of the mote has changed, using location logic, or it may recognize that the readings being given by the mote are uncharacteristic of its prior position. The system may then adapt by selecting one or more motes to replace the mote in providing readings used in the emulation.

As an example of when reading accuracy may trigger adaptation, the system may examine the accuracy of readings, either automatically or triggered by the intervention of some person or device(s). For example, a person may bring a highly accurate thermometer into the room and take readings at the two emulated locations. If the accuracy of the mote readings is not comparable, the system may adapt which and/or how many motes to use to provide readings.

As another example of adaptation, motes may be added to the system, or one or more motes in the system may have their locations moved. The system may then adapt the selection of motes to use for emulation, resulting in increased emulation accuracy going forward.

As another example of adaptation, a part of the mote environment becomes contaminated. For example, workers might respond to a small fire by spraying part of a wall or other surface with fire retardant, which may then coat the motes attached thereon. The system may recognize these motes are no longer giving characteristic readings and may then select one or more replacement motes.

Network adaptation may involve observing behavior and/or characteristics of the sensors to emulate, and refining a selection of the mote sensors, the number of mote sensors, the mote sensor locations, and/or the number of mote sensor locations in order to improve emulation of behavior and/or characteristics of the sensors. For example, motes 102-104 may provide pressure readings in a pipe 117 carrying a moving fluid. A conventional non-mote pressure sensor may also be present in the pipe. The system may observe behavior and/or characteristics of the pressure sensor to emulate, and refine a selection of the mote sensors, the number of mote sensors, the mote sensor locations, and/or the number of mote sensor locations in order to improve emulation of behavior and/or characteristics of the non-mote pressure sensor.

Network adaptation may involve selecting one or more replacement mote sensors (a.k.a. “mote replacement”) to replace one or more failed mote sensors as a source of the collected readings. Mote replacement may in some cases involve the mote network selecting one or more replacement mote sensors to replace one or more failed mote sensors as a source of the collected readings. In other cases, external logic such as logic 113 may select mote replacements.

Emulation Interface

An interface device such as device 111 may be provided to receive and/or collect readings from the mote sensors, and to convert the readings into at least one non-mote sensor reading. The device 111 may include logic to communicate the at least one non-mote sensor reading via a non-mote sensor interface. Thus, the device 111 may serve to emulate at least one non-mote (e.g. legacy) sensor via a mote network (henceforth, “sensor interface emulation”). Sensor interface emulation may include and/or involve logic to emulate a manner of communication of the at least one non-mote sensor. In other words, the device 111 may appear as the non-mote sensor(s) to controllers or other devices adapted to interact with the non-mote sensor(s).

Some applications may not employ an external device 111. Instead, the mote network itself may provide the functions of the external device 111.

In some applications the location(s) of the emulated non-mote sensor(s) may be relevant to controllers or other devices that interact with the non-mote sensors. The device 111 may include and/or involve logic to apply location information for the mote sensors that provide the readings in order to derive at least one emulated non-mote sensor location. For example, in the example of motes emulating thermocouples, the device 111 may determine two locations with which to associate the emulated thermocouple readings, based upon the locations of the motes chosen to provide readings for the emulation. In some situations the mote network itself may provide these features.

The device 111 may include and/or involve logic to select at least one mote sensor to provide the readings (henceforth, “mote sensor selection”). Mote sensor selection may involve logic to select one or more mote sensors to compensate for at least one failed mote sensor, and or logic to select at least one mote sensor to increase an accuracy of emulation of the at least one non-mote sensor. In some implementations, the mote network itself may provide these features.

The device 111 may include and/or involve logic to cause a change in at least one location from which the readings are provided. The logic to cause a change in at least one location from which the readings are provided (henceforth, ‘mote location selection’) may include and/or involve logic to deselect at least one mote as a source of the readings and to select at least one other mote as the source of the readings. This may include and/or involve logic to cause at least one mote that is a source of the readings to change position.

Process of Mote Network Sensor Emulation

FIG. 2 is an action flow diagram of an embodiment of a process of mote network sensor emulation. The motes in the network communicate with their nearest neighbors. The mote closest to the interface device passes all such communication it receives to the mote interface.

At 202 mote 1 communicates its sensor reading to mote 2. At 204 mote 2 communicates its sensor reading to mote 3. At 206 mote 2 communicates mote 1's sensor data to mote 3. At 208, 210, and 212 mote 3 communicates the data for itself, mote 1, and mote 2 respectively to the mote interface.

The mote interface then calculates the derived data value for the sensor or sensors which are being emulated. At 214, this derived data is communicated to the controller.

The mote interface has recognized that the emulation(s) may better be performed by making some change affecting mote 2, and at 216, the mote interface sends the information to perform the mote 2 adaptation to mote 3. At 218, mote 3 communicates this information about the mote 2 adaptation to mote 2.

Mote Network Sensor Emulation

FIG. 3 is a flow chart of an embodiment of mote network sensor emulation. At 302, readings from the motes participating in the sensor emulation are obtained. At 306, the emulation is performed. At 308, the results of the emulation are examined. At 310, if the results are satisfactory, at 314 the emulation is complete.

If unsatisfactory, at 312 the calculations and/or motes used may be adjusted. Additional mote readings may be obtained at 302, and the process repeats.

Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a solely software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary.

 16. The method of claim 15, further comprising: selecting one or more replacement mote sensors to replace one or more failed mote sensors as a source of the one or more collected readings.
 17. The method of claim 16, wherein selecting one or more replacement mote sensors to replace one or more failed mote sensors as a source of the one or more collected readings further comprises: mote network selecting one or more replacement mote sensors to replace one or more failed mote sensors as a source of the one or more collected readings.
 18. The method of claim 15, further comprising: the mote network selecting at least one of the mote sensor locations to improve an accuracy of the one or more derived readings.
 19. The method of claim 15, further comprising: adapting the emulating to account for one or more changes to the one or more mote sensor locations.
 20. The method of claim 15, wherein refining a selection of at least one of the mote sensors of the mote network based at least partially on the deriving: refining at least one of a selection of the two or more mote sensors from which to collect the one or more readings to improve emulation of the at least one non-mote sensor.
 21. An apparatus at least partially implemented using hardware, comprising: logic to receive one or more readings from two or more mote sensors; logic to convert the one or more readings into at least one non-mote sensor reading including increasing an accuracy of the at least one non-mote sensor reading during the conversion; and logic to communicate the at least one non-mote sensor reading via an interface.
 22. The apparatus of claim 21, wherein the logic to communicate the at least one non-mote sensor reading via an interface further comprises: logic to emulate a manner of communication of the at least one non-mote sensor.
 23. The apparatus of claim 21, further comprising: logic to apply location information for the two or more mote sensors to derive at least one emulated non-mote sensor location.
